Michael Jackson used music videos to promote his music and extend his income in several ways: 1) His "Earth Song" video from 1997 addressed environmental issues and was very successful, receiving nominations and promoting his image. 2) Footage from his planned "This Is It" concerts in 2009 was released as a documentary film, becoming the highest grossing concert/documentary ever and continuing to generate revenue after his death. 3) Jackson's website and memorabilia sales provide ongoing outlets to keep his legacy and music alive in the marketplace. His innovative videos in the 1980s helped launch MTV and influence many other artists.
